Astell&Kern A&futura SE100 | Digital Audio Player

From Astell&Kern 
A&futura is a premium line of players with advanced features that bring the original performance to life. The SE100, the first model of A&futura, is designed for you to feel the quality of premium Hi-Fi from the moment you hold it.

• Radically different sound by ES9038 Pro 8-channel DAC
• Next Level performance with Octa-core CPU
• 5-inch display with HD screen resolution and improved user interface
• Similar audio block design of SP1000 for premium Hi-Fi audio performance

A&futura SE100 shows our dedication to provide both premium quality and value to our listeners including an eye-catching design. It features a 5-inch touchscreen, Octa-core CPU, and the best audio performance in its league.Astell&Kern is committed to delivering the original performance as the artist intended you to hear and the SE100 is a symbolic example of this vision and effort.

A&futura SE100 introduces an 8-channel DAC chip. 8-channel DACs have previously only been available for premium home audio systems, pro-audio workstations, and recording studio equipment. It is making a debut for the first time in an Astell&Kern portable system. Your favorite tunes will now sound fundamentality different with even greater dynamic range and refined sound.

Maximum Output
It is common knowledge in the audio industry that the amplifier plays a critical role in Hi-Fi audio systems. The latest know-how and amplifier design technologies developed by Astell&Kern have brought 4.1Vrms of balanced output power with minimal noise. As the output power increases, the noise fluctuates louder as well. However, A&futura SE100 shows 123dB of SNR (Signal to Noise Ratio) at 4.1Vrms of audio output. At the same time, the noise level on single-ended is even smaller, it produces 122dB of SNR. Pure sound is the result in our technical achievement allowing for powerful, yet clean sound to be delivered gracefully by the SE100.

Femto-Second Clock for Exact Sonic Reproduction
An enhanced voltage-controlled crystal oscillator (VCXO) high-precision clock has been utilized in the A&futura SE100. The reference jitter of Astell&Kern's implementation has improved performance to 800fs (femto seconds), meaning that the SE100 faithfully reproduces your music by precisely measuring and accurately timing the synchronization of all instruments, vocal and even ambience sound recorded in your digital music file together.

Great Performance for the Ultimate Experience
The A&futura SE100 is equipped with an octa-core CPU which allows the player to produce the exact musical detail present in the original recording without distortion and provides a quick, lag-free operation.

The A&futura SE100 features faster booting times, speedy file transfers, lag-free processing and a new intuitive user interface for the ultimate player experience.

Ultimate Sound Quality
The A&futura SE100 supports native bit-to-bit DSD playback up to 11.2MHz for the best sound possible. The music is played back, bit-for-bit, just as the artist and engineer intended for it to be heard.
